I think it would work fine. Kinda tough to tell without seeing Jackman in it though. Looks awesome.
There was a reason for it in Aronofskys script. Without knowing how it was to be used in TW, we can't really answer that question. If Logan ever needs to hide his identity/go covert that's all the reason I need.
Wasn't it said the X-Men in the future of DOFP are wearing make up of some sort? If everyone is decking themselves out like that or in armor (which they seem to be), Logans Mask should blend in with that battle theme fine. He seems to be in a more traditional suit in the DOFP pic we saw as well.
Old thread on the subect...
